Comment 2 for bug 1656201

It didn't return control to Bash, and when I went back and killed the Juju Controller, I then also got:
exception calling callback for <Future at 0x7f37d58136d8 state=finished raised ConnectionClosedError>
Traceback (most recent call last):
  File "/usr/lib/python3.5/concurrent/futures/thread.py", line 55, in run

  File "/usr/lib/python3/dist-packages/macumba/ws.py", line 75, in do_receive
    raise ConnectionClosedError
macumba.errors.ConnectionClosedError

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/lib/python3.5/concurrent/futures/_base.py", line 297, in _invoke_callbacks
    callback(self)

  File "/usr/lib/python3/dist-packages/conjureup/controllers/deploy/gui.py", line 29, in _handle_exception
    track_exception(exc.args[0])
IndexError: tuple index out of range

At which point I *did* get the bash prompt again. Hopefully one of those tracebacks are useful.
